Missional Communities (MCs) are a hot topic right now in the church, and many are excited about the potential of MCs to be a vehicle that allows the church to better live out its mission in the world. But if we embrace and implement MCs merely as a new program, they won’t live up to their potential and we’ll be on to the next hot topic in a few months. Mcs are helpful only if we use them as a vehicle that allows us to point ourselves towards a much deeper issue: how we can learn to live our everyday lives as extended families on mission. We call this reality oikos (“household” in Greek), and that’s actually what this book is about. Think of it like this: an MC is a great vehicle, but vehicles are suppose to take you somewhere. The destination the vehicle of MC takes us to is oikos.
